Answer:

Victor's age = 24 years old

Explanation:

Let age of Mr. Smith = x and age of Victor = y.

According to the question, we can find two equations.

=> 1) x = y + 81

=> 2) x + 3 = 4(y + 3)

Substituting value of x in (1) to (2)

y + 81 + 3 = 4y + 12

3y = 72

y = 24

Victor's age = 24 years old

Answer :-

  • 24 years

Solution :-

  • Let the age of victor be X .
  • and, the age of Mr.Smith be = 81 + x

So, after 3 years = x+81 +3

  • 81 + 3 + x = 4 ( x + 3 )
  • 84 + x = 4x + 12

now grouping the variables and constants together we get,

  • 4x-x=84-12
  • 3x = 72
  • x = 72/3
  • x = 24

Thus, Victor's present age is 24 yrs.

Hope it helps ya ~
